Dianthus plant named ‘KLEDG19294’

ABSTRACT

A new  Dianthus  plant named ‘KLEDG19294’ particularly distinguished by double flowers with a magenta flower color with a purple center, a maculated flower pattern and green leaf color, is disclosed.

Genus and species: Dianthus cultivars.

Variety denomination: ‘KLEDG19294’.

BACKGROUND OF VARIETY ‘KLEDG19294’

The present invention comprises a new and distinct variety of Dianthus, botanically known as Dianthus cultivars and hereinafter referred to by the variety name ‘KLEDG19294’. ‘KLEDG19294’ is a selection that resulted from an open pollination of the proprietary female Dianthus line ‘DSS-2011-0081’ (unpatented) and the proprietary male Dianthus line ‘DSS-2008-0026’.

In May of 2012, the proprietary female Dianthus line ‘DSS-2011-0081’ and the proprietary male Dianthus line ‘DSS-2008-0026’ were cross pollinated in Stuttgart, Germany and seeds were obtained. The seeds were sown and plants were grown for evaluation. A plant line was selected in June of 2013 in Stuttgart, Germany, and named ‘KLEDG19294’. In September of 2013, ‘KLEDG19294’ was first vegetatively propagated by vegetative cuttings. ‘KLEDG19294’ was found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings in Stuttgart, Germany and Latina, Italy.

SUMMARY OF VARIETY ‘KLEDG19294’

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Stuttgart, Italy.

-   -   1. Double flowers with a magenta flower color with a purple         center;     -   2. A maculated flower pattern; and     -   3. Green leaf color.
